About this study

To determine the factors associated with progression of sub-clinical atherosclerosis and to evaluate the associations between the progression of sub-clinical atherosclerosis and the development of clinically manifest atherosclerosis.

Read the detailed description

BACKGROUND:

Cardiovascular disease remains the leading cause of death in the United States and one of the leading causes of morbidity. New technology recently has allowed the non-invasive investigation of the extent of atherosclerosis in different vascular beds. Unfortunately, the clinical implications and significance of this new technology have not yet been fully examined nor has the interrelationship between these various measurements of clinical and sub-clinical atherosclerosis. The study is ancillary to the Multi-Ethnic Study of Atherosclerosis (MESA), an NHLBI-supported epidemiological study of atherosclerosis in several ethnic groups.

DESIGN NARRATIVE:

A longitudinal assessment of the carotid intima media thickness (IMT) will be added to the scheduled follow-up visits in MESA subjects in order to study the relationship between carotid IMT and a measure of calcium burden in the coronary vessels. In addition, studies will be conducted on how these two non-invasive markers of atherosclerosis relate to cardiovascular disease risk factors and clinical events.The study will utilize the MESA cohort involving 6500 subjects who will have baseline and four follow-up examinations. coronary artery calcification (CAC) and IMT are being obtained at baseline, with CAC determinations also scheduled at follow-up. IMT determinations will be added in conjunction with the CAC studies in the second and third exams and detailed analyses will be carried out on these two measures of atherosclerotic burden that may reflect different biologic processes.

Questions about this trial

What is this clinical trial studying?

An observational study of Atherosclerosis and Cardiovascular Diseases, run by Tufts Medical Center.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Common carotid artery intima-media thickness (time frame: randomly selected at 2 years or 4 years in 1/2 of the cohort). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00063440, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Feb 2013.
